TDOMNodeList.NodeFilter function
Determines if the node can be used in the DOM node list.
Declaration
function NodeFilter(aNode: TDOMNode): TFilterResult; virtualArguments
aNode | DOM Node to examine in the method. |
Function result
Indicates if the node is included in the node list.
Description
NodeFilter is a
TFilterResult function used to
determine if the DOM node specified in
ANode can be included in
the DOM Node list. The return value indicates whether the node is allowed,
and also whether its child nodes can be examined as well.
NodeFilter always returns frNoRecurseTrue in
TDOMNodeList, and allows the node but does not allow
recursion into its child nodes. The method is overridden in descendent
classes to perform the actions needed for the DOM node specialization.
